My dad has a three and a half year old gas boiler (Halstead Best db 50 a.k.a. Wickes LW50ci). He has spent a lot of money on engineer call-outs but has yet to overcome a problem he has with the boiler. Even if no-one can give a solution, better understanding of possible faults would be appreciated.
The boiler works fine for the Hot Water (HW).
If he turns the Central Heating (CH) on (with or without HW), the boiler works for about 5 to 10 minutes then just as the top of the radiators start to go warm/hot, an Ignition Lockout Indicator comes on and the boiler switches off. If we reset the boiler according to the Halstead manual, using the Ignition Reset Button, the boiler will work for about 20 seconds before the Ignition Lockout Indicator comes on and the boiler switches off again (and so on).
I understand that a Flow Temperature Thermister has been replaced and we have replaced the Ignition Device with a second hand one, but we get the same results.
I spoke to a rep. at Halstead and they were puzzled over why the boiler works in HW mode but not CH. They suggested it might not be a boiler fault.
The only other thing I can offer is the fact that my dad does all his own DIY installations. Some time in the recent past he replaced one big radiator with two smaller ones.
If no-one could offer a solution, could someone please explain what the Ignition Lockout Indicator is alerting to? Nights are starting to get cold
Thanks in advance
